Gotcha.  Didn't realize he'd been summarizing the discussion.  Well,
I'll hold my opinion on the whole proposal pending a PEP, but I'll make
two comments on the proposal as it stands:

* I'm strongly opposed to the return idea instead of raising
StopAccumulation (which should be a subclass of StopIteration).  Using
return this way is IMO unPythonic.

* If we're using bracket notation, I think accumulators must return a
list.  I think it would be a Bad Idea to permit other types (although I'm
willing for leeway to permit list subclasses).
